By way of Brickstar on YouTube, neoape has painstakingly taken screen shots from his video of every step of the instruction manual from the San Diego Comic Con Batmobile set. You can get the Batman and Robin minifigures from LEGO Juniors 10672 Batman: Defend the Bat Cave and, according to the article, a good number of parts from LEGO City 60007 High Speed Chase . Obviously you’ll have to source the rest of the parts from your own collection or other places like Bricklink or LEGO’s part ordering system. The only thing you don’t get is the packaging. The post over at neoape has pictures of the parts list.
